Abstract: A display apparatus may include a base substrate including a first portion and a second portion smaller than the first portion, a plurality of pixels disposed on the first portion, a protection substrate disposed below the base substrate, and a groove disposed in a portion of the protection substrate and overlapped with the second portion. The groove may include a first region extending in a first direction, and a second region and a third region, which are arranged along the first direction, wherein the first region is interposed between the second region and the third region. The first and second portions may be arranged in a second direction crossing the first direction, and a width of each of the second and third regions may be larger than a first width of the first region, when measured in the second direction.

Abstract: A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.
